  • Patent number: 7440058
    Abstract: A liquid crystal display panel (LCD panel) includes an active component array substrate, an opposite substrate and an optically compensated birefringence type liquid crystal layer (OCB-type liquid crystal layer). The active component array substrate includes a first substrate, a plurality of first lines, a plurality of second lines, a plurality of pixel structures and a first alignment layer. The first alignment layer possesses a first orientation direction, and the included angle between the first orientation direction and the first lines is between 46 and 74 degree. The opposite substrate has a second alignment layer facing the active component array substrate, and the second alignment layer possesses a second orientation direction parallel to the first orientation direction. The OCB-type liquid crystal layer is disposed between the active component array substrate and the opposite substrate.

  • Publication number: 20070057891
    Abstract: A method for the transition of a liquid crystal display is provided. The liquid crystal display includes a liquid crystal panel including a first electrode, a second electrode and a vertical alignment liquid crystal layer between the first and second electrodes. The method includes performing a pre-driving step including applying a reference voltage on the first electrode and applying a driving voltage on the second electrode so as to form an electric field between the first and second electrodes, wherein the frequency of the driving voltage is a voltage level variation frequency.
